NORTH BAY, Ont. — Eleven train cars derailed in northern Ontario Monday morning, including one carrying a load of methanol and three empty residue tank cars that were previously used to transport sulphuric acid.

The crash occurred about 60 km south of North Bay near South River.

The Canadian National Railway said there were no injuries and none of the cars leaked. The car carrying methanol remained upright, the company said.

The other seven cars were carrying general merchandise and consumer goods.

A company spokeswoman said the cause of the derailment hasn't been determined.

The issue of rail safety made international headlines in July when a crude-carrying runaway train derailed and exploded in Lac-Megantic, Que., killing 47 people and incinerating a large chunk of the town's core.
